Encrypting partitions using dm-crypt
"dm-crypt provides a crypto layer for Device-mapper. A Device-mapper driver allows you to define new partitions or logical volumes by specifying ranges of sectors on existing block devices. The ranges of sectors to be used by these partitions is mapped to targets according to a mapping table. dm-crypt provides just such a target which can be used to transparently encrypt a block device using the new 2.6 kernel cryptoAPI."
